Switch zoning limitations for IBM XIV systems

There are limitations in switch zoning for Storwize® V3500 clustered systems and IBM® XIV® Storage System systems.

Fabric zoning

To avoid a single point of failure, the Storwize V3500 switch zone must include at least one target port from each IBM XIV Storage System controller.

Target port sharing

Target ports can be shared between the Storwize V3500 system and other hosts.

Host splitting

To avoid the possibility of an interaction between multipathing drivers, a single host cannot be connected to both the Storwize V3500 system and the IBM XIV Storage System system.

Controller splitting

IBM XIV Storage System system LUNs that are mapped to the Storwize V3500 system cannot be mapped to other hosts. IBM XIV Storage System system LUNs that are not mapped to the Storwize V3500 system can be mapped to other hosts.
